vention being an improvement in the struc- :5 Hire and organization ofthe safety and actu ating means, having for its object thesimplification of the mechanism and processes of its manufacture, and toprovide a safety slid-- i'ng hammer-face that is;directl y engaged and3c operated by the hammer-lifter pawl, the engaging detents, lugs, orsurfaces being portions of said slide and lifter, acting upon each etherby immediate contact or without any intervening separable member ormembers, 5 as more fully hereinafter explained. I attain these objectsby the mechanism shown in the "drawings, wherein- Figure 1 is aside'view of a double-action revolver embodying my invention, the side ofthe frame beingbroken away to reveal the leak devices. Fig. 2 is asectional view showing the front of the hammer, the lifter-pawl, &c.,with dotted. lines indicating the relative positions of the frame andcylinder. Fig. 3 5 is a vertical sectional view illustrating thepositions of the parts at the instant, of discharge. Fig. 4 illustratesthe manner in which the lifter retains the hammer-face at the positionof safety. Fig. 5 shows side and front detail views of the slidinghammerface separate from other parts; and Figs. 6, 7, and 8,

An example illustrate{modifications in I the form of the safety parts. yt

In practice my invention is-applicahle to a revolveror double-actionfirearm, whichin.

its general construction may be of well-known form and character, asshown in the drawings. v 7,

the side of the lifter and M denotes the 'mainspring, which aetuatesthehammer-in the manner heretofore practiced. v i The part marked Irepresents the safety member or sliding; hammer-face, which inaccordance with my inventionis providedat its front with an upperengaging lug, offset,

or shoulder 3 and alo wler engaging lug, off- .set, or shoulder 5,formed directlyin or upon the sliding face p'ieceisee Fig. 5) and havinga recess or space 4: between said lugs orshoulders. Saidslidingface-piece is also formed with a straight rear edge and'a suitable cou-'tact-face for impingement on the firing-pin head. t The hammer-body hasthe groove h formed in its front edge and extending down to the tumbler,and said sliding hammer-face is fitted and secured in said groove toslide up and down therein and in such relation that the aforesaid lugs,offsets, or shoulders 3 and 5 immediately coact with the end or lug ofthe lifter-pawl J for operation of the sliding facepiece Without anyintermediary member or 5' separate coupling part, thereby rendering theoperation of the sliding hammer-face direct from and by the lifter, andthe construction simple and of the least number of parts.

The sliding member I is provided with a longitudinal slot 11 and isretained in slidable connection with the hammer-body by a pin 6,

inserted transversely through the parts, as

\ illustrated, the slide being otherwise independent and free forcontrol by the lifter.

' The lower offset or shoulder 5 corresponds with the bottom of therecess G in the hammer-body, or is so located as to be engaged by thelug or nose on the lifter 3 when the trigger and said lifter are atnormal position, and in the event of the hammer being drawn back (seeFigs. 1 and 4:) the part I is thereby kept at a position of safetyshould the hammer fall unintentionally. hammer-face is at depressedposition, the

front of the hammer presents a space into which the head of thefiring-pin is received without effecting contact therewith; but whenelevated the hammer-face presents a solid portion that contacts with andforces forward the firing-pin to discharge the cartridge.

When the trigger is pulled back, as for regular discharge, and reachesthe point at which the hammer is released, the lug or end of the litteris at such elevation that it impinges I against and beneath the upperlug or shoulposition for contact with the firingrpin head,

der 3 on the sliding hammer-face and as the hammer drops forces saidsliding face 1 into as illustrated in'Fig. 3.

Figs. 6, 7, and'S illustrate a modified form of the sliding member-inwhich the lower porand 5 with each other, which bar may in someinstances be desirable, as it can limit the forward swing of the lifteras it throws from the hammer in a quick self-cocking action.

I do not herein claim, broadly, the idea of When the sliding a slidinghammer-face controlled from the trigger, since such an idea in adifierently organized construction is disclosed in the Letters Patenthereinbefore noted; but my in vention comprises the improvedconstruction whereiirthe lifter directly actuates the sliding-facemember without an intermediately disposed member.

What I claim, and desire tosecure by Let ters Patent, is

1. A sliding hammer-face provided with per and under lugspifsets orshoulders adapted for direct engagement with the lug or end of thelitter; in combination, with the pivoted hammer-body having said slidinghammerface mounted thereon for moving into and from contact positionwith the firing-pin, the lifter adapted for im pingement on saidhammer-face lugs or shoulders, byits upward and downward movements, andthe trigger carrying said lifter.

2. The sliding hammer-face fitting within the vertical groove in thefront of the ham mer-body, and adapted for moving into and from positionof contact with the firing-pin, said hammerface provided with atransverse longitudinal slot and with upper and under engaging lugs,offsets or shoulders, the latter coinciding with the bottom of thelifter recess, when depressed, in combination with the hammer-body, afastening-pin through said body and sl0t,.the firing-pin, the swingingtrigger, and the lifter hinged to said trigger and adapted for operativecontact directly with the engaging lugs or shoulders on said slidinghammer-face, substantially as set forth. g
